-3 + 3n = -6 - 6n. Expand the brackets
3n + 6n = -6 + 3. Collect like terms
9n = -3
n = -3/9 = -1/3
Answer:
a . 34
b. 150
Step-by-step explanation:
in the second case firstly add the number in bracket and multiply both the number given
in 1st case first multiply
then add both the product
Answer:
B. 
Step-by-step explanation:
GIven that
and
, and that point M is the midpoint of AB, the midpoint can be determined as a vectorial sum of A and B. That is:

The location of B is now determined after algebraic handling:


Then:




Which corresponds to option B.
For this case we have the following multiplication:

We can rewrite this operation to facilitate the calculation.
We have then:

From here, we apply the distributive property.
We have then:

Rewriting we have:

Finally adding all the numbers we have:

Answer:
The value of 6 * 298 is 1788 and the calculations can be provided as follows:
